Scientists 3D-print glass nanostructures with near-100% reflectance
Using a newly developed resin and a high-precision printing process, researchers have fabricated nanoscale glass structures that achieve nearly perfect light reflectance, opening up new possibilities for the material in advanced optics.
Age of oldest known human footprints in Americas confirmed by new study
By analyzing ancient mud, scientists have added a powerful new line of evidence confirming that humans walked in North America during the peak of the last ice age.
Ancient leaf waxes reveal a wetter African past than dust records suggested
New evidence from ancient leaf waxes reveals that northern African summer rainfall remained stable even as the world plunged into an ice age, challenging a long-held view of the continent's climate history.
Scientists develop a ‘prism for sound,’ turning noise into an acoustic rainbow
Researchers have developed a novel device that splits a mix of sounds into its constituent frequencies, essentially creating an “acoustic rainbow.”
